Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a connector. Background Technology

[0002] Current connectors require a Connector Position Asurance (CPA) structure to ensure proper connection and prevent accidental disconnection. In some CPA structures, after the locking handle and the push-button latch are engaged and locked, the position assurance component can only prevent the push-button latch from being pressed when it moves to the locked position; it cannot simultaneously lock the locking handle directly. In this case, the locking handle still carries the risk of accidental unlocking. Utility Model Content

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] like Figure 1-9 As shown, an embodiment of the present invention provides a connector, including a connector housing 1 with a locking device 2. The connector housing 1 is provided with a press-lock 11 and a position guarantee member 3. The position guarantee member 3 is assembled on the connector housing 1 and is provided with a first blocking part 31 and a second blocking part 32. After the locking device 2 moves and engages with the press-lock 11, the position guarantee member 3 moves so that the first blocking part 31 at least partially engages with the press-lock 11 in the pressing direction, and the second blocking part 32 at least partially engages with the locking device 2 in the opposite movement direction.

[0037] As a common method, such as Figure 1-4 As shown, in this embodiment, the locking device 2 is rotatably mounted on the connector housing 1. After the locking device 2 rotates and engages with the press lock 11, the moving position guarantee member 3 makes the first blocking part 31 engage with the press lock 11 in the pressing direction, and the second blocking part 32 engages with the locking device 2 in the opposite rotation direction of the locking device 2.

[0038] Obviously, in other embodiments, the locking device can also be slidably disposed on the connector housing in a predetermined direction. After the locking device slides and engages with the press latch, the moving position guarantee member makes the first blocking part stop engaging with the press latch in the pressing direction, and the second blocking part stops engaging with the locking device in the opposite sliding direction of the locking device.

[0039] Furthermore, such as Figure 8 As shown, in this embodiment, the locking device 2 includes a locking part 22 and rotating parts 21 disposed at both ends of the locking part 22. The locking part 22 is engaged with the press-lock buckle 11, and the rotating part 21 is rotatably connected to the connector housing 1. The rotating part 21 is provided with a gear 26 that meshes with the rack of the mating connector. By rotating the locking device 2, the meshing of the gear 26 and the rack allows the connector to be connected and locked with the mating connector. In fact, the locking device 2 in this embodiment is a locking handle commonly used in the art. This locking handle can also be called a locking lever, operating rod, handle, pull handle, lever, or auxiliary handle, and belongs to common technology in the art.

[0040] In addition, such as Figure 1-8As shown, in this embodiment, the locking part 22 is provided with a locking hook 23, and the pressing latch 11 is provided with a mating hook part 12 corresponding to the locking hook 23. After the locking device 2 rotates, the locking hook 23 and the mating hook part 12 engage to achieve the engagement between the locking device 2 and the pressing latch 11. That is, the pressing latch 11 locks the locking device 2. When unlocking, pressing the pressing latch 11 forces the mating hook part 12 to release the engagement with the locking hook 23. At this time, the pressing latch 11 releases the locking device 2, and the locking device 2 can rotate in the opposite direction, thereby allowing the connector to disconnect from the mating connector.

[0041] As a relatively stable and mature assembly method, in this embodiment, the position guarantee component 3 is slidably assembled onto the connector housing 1. For example... Figure 5 , 7 As shown in Figure 9, the connector housing 1 is provided with a slide rail 16, and the position guarantee component 3 is provided with a slide groove 36. The slide rail 16 and the slide groove 36 are slidably assembled to realize the sliding assembly of the position guarantee component 3 and the connector housing 1. The cross-section of the slide rail 16 and the slide groove 36 is an adapted L-shaped structure to avoid the position guarantee component 3 from disengaging from the connector housing 1. There are two pairs of slide rails 16 and slide grooves 36.

[0042] Of course, in other embodiments, the position guarantor can also be mounted on the housing in other ways that can be achieved by conventional technology, as long as the movement and predetermined functions of the position guarantor 3 can be realized.

[0043] Furthermore, in order to save design space, reduce the expected size of the connector, and make the engagement between the first blocking part 31 and the press-lock 11 more stable, such as Figure 3 , 4 As shown in Figures 7 and 8, in this embodiment, the press-lock 11 is provided with a lock slot 14, and the first blocking part 31 is at least partially inserted into the lock slot 14 to achieve the blocking cooperation between the first blocking part 31 and the press-lock 11 in the pressing direction.

[0044] Furthermore, in order to save design space, reduce the expected size of the connector, and make the fit between the second blocking part 32 and the locking device 2 more stable, such as Figure 2 , 8 As shown, in this embodiment, the locking device 2 is provided with a locking slot 25, and the second blocking part 32 is at least partially inserted into the locking slot 25 to achieve the blocking cooperation between the second blocking part 32 and the locking device 2 in the opposite movement direction.

[0045] Furthermore, to prevent the position guarantee member 3 from moving when the locking device 2 is not engaged with the push-lock 11, and also to prevent the position guarantee member 3 from moving in the opposite direction after it has been moved into place, that is, to ensure that the position guarantee member 3 can be positioned in the initial position before movement and the locked position after movement, such as Figure 1-9As shown, in this embodiment, the position guarantee member 3 is provided with an elastic hook 33 extending in the moving direction, and the connector housing 1 is provided with a positioning block 13. The positioning block 13 and the hook of the elastic hook 33 are engaged in a blocking engagement in the moving direction. At this time, the position guarantee member 3 is located in the initial position. The locking device 2 is provided with a push block 24. The push block 24 moves with the locking device 2 and pushes the hook to release the hook from the blocking engagement with the positioning block 13. The position guarantee member 3 is moved so that the hook passes over the first positioning block 13 and engages in a blocking engagement with the first positioning block 13 in the opposite moving direction. At this time, the position guarantee member 3 is located in the locked position.

[0046] Furthermore, to enhance the positioning of the position guarantee component 3 in the initial and locked positions, such as... Figure 5-7 and Figure 9 As shown, in this embodiment, the connector housing 1 is provided with a limiting block 15, and the position guarantee member 3 is provided with a first protrusion 34 and a second protrusion 35 at intervals along the moving direction. The first protrusion 34 and the second protrusion 35 are clamped at both ends of the limiting block 15. At this time, the position guarantee member 3 is in the initial position, or in other words, at this time, at least the second protrusion 35 and the limiting block 15 are in a blocking engagement in the reverse moving direction, so that the position guarantee member 3 is in the initial position. After the position guarantee member 3 is moved, the first protrusion 34 passes over the limiting block 15 and is in a blocking engagement with the limiting block 15 in the reverse moving direction. At this time, the position guarantee member 3 is in the locked position.

[0047] In addition, when the position guarantor 3 is in the above-mentioned locked position, the position guarantor 3 and the locking device 2 are in a blocking engagement in the moving direction, thereby preventing the position guarantor 3 from continuing to move in the moving direction when in the locked position.

[0048] Furthermore, to enable the connector to be identifiable, facilitate the provision of product information to the inspection agency, and prevent the inspection agency from identifying the connector's product information when the position guarantee 3 is in its initial position, such as... Figure 2 , 6 As shown, in this embodiment, the connector housing 1 is provided with an identifier 4 that is at least partially covered by the position guarantee member 3. After the position guarantee member 3 moves, the cover of the identifier 4 is released. That is, when the position guarantee member 3 is in the initial position, the identifier 4 is at least partially covered. When the position guarantee member 3 moves to the locked position, the identifier 4 is fully exposed. The identifier 4 can be directly formed by identifiable symbols or graphics such as codes or QR codes. The identifier 4 can also be an adhesive sheet structure, on which identifiable symbols or graphics such as codes or QR codes are set.

[0049] Furthermore, in order to effectively occlude the identifier 4 when the position guarantor 3 is in the initial position, the position guarantor 3 occludes at least 50% of the area of ​​the identifier 4 when it is not moved, that is, when it is in the initial position.

[0050] The usage and operation of this connector have been demonstrated through the above description of the structure, and those skilled in the art can obtain and understand the usage and operation of this connector through the above description and drawings, therefore, they will not be described in detail again.
